Seizure disorder also known as epilepsy, is a neurological condition in which the brain's abnormal electrical activity causes muscular convulsions and altered mental states. Epilepsy is diagnosed when an individual has two or more seizures.

Very unlikely:
Seizures can be triggered by specific stimuli such as flickering light or hyperventilation. Fever in a toddler is associated with a toxic state that can cause a seizure. Heat alone is very unlikely to cause a seizure. Being aware of early signs of a seizure is very important. Avoiding stimuli that can bring on a seizure is important. These must be part of seizure management.

Phenobarbital:
Phenobarbital and febrile seizures are controversial. Unless the seizures were long or atypical often rectal Valium is given to stop the seizure. Ask your doctor if he needs the medicine or if there are other options.

Excitable brain cell:
Anything that causes brain cells to be irritated or overexcitable can cause a seizure. Genetic causes of epilepsy that lead to an abnormality in excitability of neurons or miswiring of connections can cause seizures. Also, any scar or lesion on the brain can cause seizure. Infections and other conditions that alter the body's normal chemistry can cause seizures.

Seizure causes:
There are around 200, 000 new seizures and epilepsy cases each year, and a cause is only identified in about 30% of those cases. The most common causes include stroke, brain tumors, head injuries, genetic conditions, infections, abnormal sodium or blood sugar levels, etc. Certain factors known to provoke seizures include missing medication doses, alcohol/drugs, sleep deprivation and stress.

Over active neurons:
A seizure is when the brain cell allows too much sodium or calcium and water follows, disrupting the flow of chemicals and waste products through special "gates." seizure meds are "gate blockers" to stop this from happening.

Unknown:
When nerve cell in brain fires electrical discharges abnormally, these discharges affect other nerve cells. Our brain has protective mechanism to avoid spread of those discharges. One cause is failure of the mechanism, why one nerve cell fires abnormally is stll not completely answered. Many researches are going on and more and more new informations are coming up but still no final answer.

Possible causes:
Many things can cause a seizure for a 16-year old (alcohol, prescription medicine, head injury) but the most common is a condition called juvenile myoclonic epilepsy. A neurology evaluation and an EEG test are very helpful for determining this. Good luck!

Electric:
While all epileptic seizures are caused by electrical disturbances in the brain, there are many kinds of seizures. See http://www.Epilepsyfoundation. Org/livingwithepilepsy/parentsandcaregivers/parents/typesofseizures. Cfm for more information.

For some people, yes:
There are some people who have a seizure in response to a particular flickering light frequency, which may be seen in video games or television. It happens even when the eyes are closed (!) These people have a generalized epilepsy, like juvenile myoclonic epilepsy.

Rarely:
There is a rare but very specific type of epilepsy that is photo sensitive. In some just the flashing of light at a specific frequency can cause a seizure. In very rare cases a specific pattern will set off seizure activity. A type of baboon (papio-papio) has a genetic tendency for photosensitive epilepsy. They have been studied in detail. Coated glasses can help.

Cause of seizures:
'Opinion not a decision'.
Every shake is not a seizure; all seizures do not shake.
Seizures have many causes including: alcohol and alcohol withdrawal; drugs; prescribed medications; brain injury; stroke; brain tumor; family history of seizures; brain infections; metabolic encephalopathy.

Cause of seizures:
Seizures are caused by anything that irritates the surface of the brain. This can be an infection, a disease of the brain, an injury, medications, alcohol or drugs, changes in the blood chemistry, etc. For some people, the cause is related to how the brain makes electricity, but this is most often the case for children, rather than adults.

An epileptic focus:
Hughlings jackson described how a focus in the brain can start a seizure that can march along the motor strip producing a progression of seizure activity. This became known as the jacksonian march. A focal scar or lesion can set this off usually on the very outer surface of the frontal lobe of the brain.

Photoparoxysmal resp:
Photoparoxysmal responses (ppr) is an abnormal visual sensitivity of the brain in reaction to intermittent photic stimulation.
Photosensitivity depends on the intensity, the contrast of the visual stimulus, and the specific frequency of flashing. The flashing patterns of certain games and television shows trigger epileptic seizures in only 5% of epileptics. Photosensitive epileptics peak at 10-14.

Long seizures:
Status epilepticus is a convulsive state in which the usual mechanisms by which the brain terminates seizures fail to operate. Hence, the seizure persists quite long and is often fatal or severely debilitating. Status can start just like any other seizure, but just keeps going.

Depends:
This depends on what you mean by a seizure. An electrical seizure (two or more make the definition of epilepsy) is not provoked by pain or shock. But symptoms that look like a seizure can be caused by pain, shock, past trauma, malingering, etc. These are called non-epileptic seizures, and in them, the brain waves do not show significant aberrant discharges.

Child or adult?:
Causes of seizures in infants and children can include a high fever and a condition called pku (phenylketonuria). In adults, there are many possible causes including brain tumor, low blood sugar, head injury, some illegal drugs (pcp, cocaine, "speed"), stroke, toxemia of pregnancy, epilepsy, and many more. If someone has a seizure for the first time, a doctor needs to do tests to find out why.

Let me explain:
Although the underlying causes of epilepsy are usually not known, certain factors are known to provoke seizures in people with epilepsy. Avoiding these triggers can help you avoid seizures and live better with epilepsy:
missing medication doses
heavy alcohol use
cocaine or other drug use, such as ecstasy
lack of sleepother drugs that interfere with seizure medications.
